IMPROVEMENT IN SASH-BALANCEVS.

u Specification forming part of Letters Patent No. 154,597, datedSeptember 1, 1874;. application tiled June 20, 1874. v

To all whom it may concern:

Be it known that I, LEwrs .FEGLEL of Port Carbon, in the county ofSchuylkill and State of Pennsylvania, have invented a new and valuableImprovement in Sash-Balances and I do hereby declare that the followingis afull, clear, and exact description of the construction and operationof the same, reference being had to the annexed drawings making a partof this specification, and to the letters and figures of referencemarked thereon.

Figure l of the drawing is a representation of a front view of mysash-balance, and Fig. 2 is a sectional view. Figs. 3 and 4 are det-ailviews.

This invention has relation to sash-balances, wherein are usedsaslrcords, passing over pulleys in the window-frame, and on the sashesto which the said cords are attached, whereby, when the lower sash israised, the upper sash will be lowered, and vice versa. The noveltyconsists in a windlass for windin g up the sash-cord, which windlass isapplied in its bearings so as to have endwise play, whereby a tooth,upon a crank-arm rigidly secured to the end of the windlass-shaft, maybe engaged with or disengaged from a toothed rack upon a face-plate ofthe windlass-case, thereby admitting of the sashes being balanced, or ofeither of them being lowered or raised independently of the other. y

In the annexed drawings, A designates a window frame., into which areset in the usual wellknown manner an upper sash, B', and a lower sash,B. a a designate groovcd pulleys, which are rigidly secured at eitherend of the top rail of the lower sash, B, and b b designate groovedpulleywheels, applied in pairs on each side of the window-frame and atthe top part thereof. O designates a semi-cylindrical hollow cover for awindlass, consisting of a rounded top, d', and two closing portions, cc', for the ends thereof, and which also afford bearings for the shaft`of the said windlass. ff are flanges constructed upon the edges of thecover C, whereby it is conveniently and rigidly secured to the top railof the lower sash B. The front end e of the cover C is circular in form,and it is provided with a circular toothed rack, g, for a purposehereinafter to be explained. D rcpresents a winding-drum, having flangesh constructed upon both ends thereof, which will prevent the sash-cord,when being wound around its periphery, from becoming engaged with theactuating shaft or its attachments. The said drum is applied within theVcover C, and has bearings for its shaft t' in tne ends e e thereof. Edesignates a crank-arm, having a handle at right angles thereto, bymeans of which it is actuated, which crank-arm is rigidly secured to theshaft tin any suitable manner, and is provided with atooth, j, upon itsunder surface, to engage with the toothed rack g, for a purpose hereinafter to be explained. Through the periphery of the winding-drum D aperforation, d', is made, through which is passed a sash-cord, f', ofsuitable length and strength, whicn passes thence over the pulleys a a',and then over the pulleys b b', and it is then rigidly attached to theupper ends of the top rail of the upper sash B. If the slack of thiscord be now taken up vby working the windlass, and the tooth j of thecrank-arm E be engaged with the tooth-rack g, by pushing the windlassinward, so as to keep the said cord properly tense, the sashes B Bl willbalance one another, so that if the one be raised the other will belowered. The two sashes being in the position shown in Fig. 1, the lowersash may be raised by operating the winding device, irst pulling thewinding-crank outward to release the tooth from the rack, and it may beheld in any desired position by bringing the tooth j and rack g intoengagement, as above described. The two sashes being in the position asabove indicated, the upper sash may be lowered by disengaging'the toothj from the rack g, and secured at any desired elevation by re-engagingthe tooth and the rack.

I' have described the windlass cover and frame as being constructed ofseparate pieces, which were subsequently united, butImay, if I soprefer, cause them to be cast in one piece.

F designates a hollow rectangular bolt-holder, which is cast upon theupper surface of the windlass-cover C, and has in its rear end, and onits upper surface, a longitudinal slot, k. Within this bolt-holder, inthe hollow portion-thereof, is applied a bolt, Gr, around the shank ofwhich is coiled a spring, Z, and upon which is rigidly secured a stud,m, by means of which the said bolt may be retracted when desired. Theouter end ofthe bolt G is adapted to be engaged with a catch, n, whichis rigidl;r secured to a suitable portion ofthe upper sash, and which,when thus engaged, will prevent either sash from being readily loweredor raised from the outside.

What I claim as new, and desire to secure by Letters Patent, isy l'. Ina device for balancing WindoW-sashes, the combination, with the sashes BB ,pulleys a a b b', of a sash-Windlass, perforated for the passage ofthe cord f and having endWise play, for the purposes set forth,substantially as specified. Y

2. The combination, with the sash-balancing` endwise-moving`Windlass-shaf't i, of the rack g and toothed crank E, substantially asspeciied.

3. The Windlasscase for balancing Windowsashes, having a lratchet-faceand journalseats, in combination With an endwise-lnoving Windlass-shaft,and a pawl-crank rigidly connected thereto, substantiallT as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
